Realistic PRO-16A manual Operation, Priority, SCAN RATE Scan Speed, Scan Delay

OPERATION

After power and antennas are connected and a crystal (or crystals) has been installed, your PR0-16Ais ready to use.

Turn VOLUME "on", by rotating to the right. Rotate SQUELCH fully counterclockwise. Set all the Channel Lock-out Buttons "on" (press in). You should hear a rushing sound from the speaker. Now adjust SQUELCH clockwise until you no longer hear the rushing background noise (fu rther explanation of SQUELCH adjustment is noted below).

If you want the PR0-16A to continuously scan the channels for which you have crystals installed, you must adjust SQUELCH as instructed above, then press SCAN/MANUAL button in, to the SCAN position. The PR0-16A will constantly scan each channel in sequence; when a signal appears on one of the channels, the receiver will lock onto that channel and you will hear the signal.

If you do not want automatic scanning on one or more channels, press their Channel Lock-out Buttons "off" (press in to release the button so it pops out).

If you want to stay tuned to one channel only, press SCAN/MANUAL button again to make it pop out to the MANUAL position. The Receiver will stop automatic scanning; now press MANUAL SELECTOR button to advance to the channel you want to listen to (as indicated by the Light). For MANUAL scanning, the receiver can be either "squelched" or "unsquelched", for Automatic scanning, SQUELCH must be set to eliminate the background noise .

To eliminate the annoying background noise, rotate SQUELCH clockwise until the background noise just stops. You can't adjust SQUELCH properly while listening to a station, so wait till signals cease. If you set SQUELCH as noted above, the PR0-16A will appear "dead" until a signal comes in; when a signal comes in, the Squelch circuit "opens up" and you hear the signal. When the signal ceases, the Squelch circuit "closes" and cuts out all sound until the next signal comes in.

PRIORITY:

In most areas there is usually one channel you will want to monitor consistently. The Priority function allows you to do this and yet you can still scan all the other channels.

When the PRIORITY Button is pressed in, the scanner w ill operate as usual-scanning across channels 1 thru 16 looking for an active channel. However, if it should stop on any channel other than the priority channel for more than two seconds, the Receiver will automatically scan back and check the priority channel.

This priority channel sampling occurs almost instantaneously and if the priority channel is not active, the scanner returns to the channel being monitored previously. This scan-back takes only six -hundredths of a second, so there is scarcely any interruption to the signal you were monitoring.

If the priority channe l is active, the scanner will continue to monitor it until it clears, and then return to the channel previously being monitored.

SCAN RATE (Scan Speed):

You can vary the scanning rate from about 10 to 20 channels per second by adjusting SCAN RATE. Use the setting that seems best for your needs. It is particularly useful when using PRIORITY-youcan get rapid scanning, plus fast scan-back checking of the Priority channel.

SCAN DELAY:

The PR0-16A has a built-in 2 second delay feature which virtually eliminates missed replies . This circuit holds the Receiver on the channel you are monitoring for a period of 2 seconds after the carrier has gone off the air, before it resumes normal scanning funct ion. This
